Goldie's Ice Cream Shoppe in Prairie City is a great place to stop for lunch and soft serve ice cream when visiting the Neal Smith Wildlife Refuge nearby. They have three seating options - outdoor tables, enclosed patio tables or indoor tables.
The kids' menu has four options. The chicken was a hit with my kids.
This is a photo of the new patio area, which greatly increased the seating options. There's also a drive-thru if you don't want to mess around with unbuckling your kiddos.
